Cisco 3560-CX cant ping between VLANS

kingsley123

Level 1

I am just running up a new 3560-CX lab switch to play with and having some issues.

Scenario:

- VLAN 10 clients cant ping VLAN 20 clients and vise versa.

- Both clients can be pinged from switch (confirming its not windows firewall)

- Both clients can ping both VLAN 10 and VLAN 20 SVIs from the command prompt.

- Clients have correct SM and default gateways configured of the relevant Switch SVI

-IP routing enabled

 

Switch is brand new, configured out of the box with the below config. Thoughts on what I am missing? Is there something specific to the CX platform that differs from the older router/switches?
